I've never posted anywhere like this before, so I'm not sure it's even in the right place; but here's hoping!
I've seen a few other threads with the same problem: A message saying "VIRUS ALERT!" is showing in my time box, and also in the "Registered to" section about My Computer properties. Also, the C: drive doesn't display in My Computer, and the Programs option isn't in the start menu. I'm running on XP (SP2 I believe...?!)
Right, I've seen that it's frowned upon to do anything before being told to, so I'm just waiting here a bit helpless to be honest... Any help vastly appreciated. Thank you
